DIKE' on REVETMENT.

Application med May` 2, 1927. v`seriar1va 183,194.

This invention .relates to dilzes or revetmentsV of that class employed in the pro-i tectionl of the banks of rivers and for reclamation. work and for eecting changes inf the course or channellof such streams, and` risen substantially above the mat and tiek poles secured thereto, and has thereto-re made it diiicult or impossible to nail the screen poles .to the tie `,poles and hence anchor the 'formersecurely and dependably to the mat. Heretoo-re, under such conditions, lthe Work `would have to be abandoned temporarily at a considerableinancial 'sacriiee or-,sometimes at undue expense, a malieshit repair-#effectedwhich could safely he dependedupon to retaini its position.`

My ohjectisato ,provide amethodo'l and means for eli'ecting al strong and ydependable connectionof the' screen poles tofthe ymat even should-:the latter be submergedaoot or two, more or less, under Water and ai Ylurther obj ect is to accomplish thisresnlt quickly and inexpensively. y

' Referring-now'tothefdraW-ing vin detail,

A, B and C respectively indicate the different rows of a series of piles v1, which are permanently driven into the bed of the' stream to be equipped with a dike orrevetment, and to form a part of such structure. The row A indicates the row of piling on the upstream side, the row C, the row olf piling, on the downstream side, and the row 13, the piling intermediate therows A and lC, it being understood of course that `many more o-tlierowsof pilingr may be utilized according to the character ofthe Work and other conditions which may suggest the advisability of a 'few or many rows of piling.

The r.rows of piling are braced'longitudinally and laterally respectively by braces 2 and 3, bolted or otherwise securely fastened to the piling, the undermo'st row olI braces, both vthe longitudinal and transversebraces, beingsecured as close to the water-line at the time of theerection yotheydile or revetment, as possible.

Tostilen/the strueture, it may be Wise braced, as for example, by means of diagonal braces 4 which preferably extend downwardlyfrom the upper ends of the pilesof row- A to a point adjacent'the Water'- line, to the piles of row C; f f l u A mat 5 vof the `desired area, isnoW Woven of .tyvigs,s1branches, flexible poles andthe li'ke,\oruofr any equivalent material, the construction being effected on` the surface'of the Water and around the piling, themat at Opposite sidesA of the vdike being Wovenon a barge and fed off the upstream end thereof as common in the: art, vvhile the portion oi'ithe mat between-and adjacent the piles is Woven' by men Working from temporary platforms (not shown), suitably supported the lateralbraces3 or other. parts of the structure `asfi'ound,mest convenient, as willy vbe readilyunderstood-` After the. mat, orthat portion or it corresponding substantially iny areayto the piling, iscompleted and resting on `the surface `ofthe Water, as explained, a series A,of longitudinal tie poles 6 areplaced upon the mat and aretightly secured thereto adjacent the upstream side of the row of pil-es @,sothat the Jforce of the eur-rent tending to loes-n rthe tie poles will lbe resisted ley-abutment olf the poles against said row of piles, it being alsonoted'that thepreferable mode of securing-tlietiefpoles in position, is by means of Winding Wirelo'ver the polesand through i otherthe mat, as indicated at 7. It willy be evident that when the tie poles 6 have-been 'secured to the mat as set out, they effectively con-y stitute a part of the body of themat itselt as they are permanently ands'ecure'ly fas" tened in place. Y y y Assuming that after the work has progressed to the extent described, the water level rises from the water-line A, to the water-line B, for example, the weight'andr friction ot the mat and tie poles on the piles plication above identified, that is, by nailing` the screen poles to they tie poles, after the former have been i'iorced down through the mat, as indicated in Figures 2 and 3."

It is necessary' for proper anchorage of the screen poles against which filling material caused by erosion or otherwise rwill accumulate, to secure them iirnily against working upward out of the mat and iioating away. as above stated, this is accomplished by nailing or otherwise securing the screen poles to the tie poles at or above the water level. in this case, assuming the tiepoles to be submerged vwith the mat, the screen polea-after being thrust through the mat as above stated, are fastened together or in series by longitudinal bars 9 in a plane above the water level, the screen poles being nailed or otherwise securely fastened to the bars. The barsv are then fastened securely yto the tie poles by means of wires 10. looped around said bars and the tie poles, therworkmen to accomplish this purpose, reaching under water and threading the wires between the mat and tie poles and then fastening the wires upon and above the bars twisting or otherwise fastening the ends of the wires together as at 11. Y

It will be evident that the,y screen poles when thus secured to the mat andtie poles,

will project above the tops of the piling, as

indicated in Figure 2, a distance substantially equal to the depth of the water below the mat, and in order to spacethe' upper ends of the screen poles to'hold them in proper y,relative position until the mat has settled to the bottom ot the stream, as will hereinafter appear, a series of horizontal spacers 12 are nailed to each sectionof the screen construction between adjacentlateral rows'of piling, it being understood that f the connection between the screen poles and the spacers, is such as to allow for irregularities in the surface of the screen vpole structure, upon the sinking of the mat, which is nowgradually weighted by piling stone as at 18, or the like, uponthe mat, the operation commencing at the` upstream edge of the mat and progressing down stream as is In the co-pendng application common in the art. The sinking of the mat 1 will. carrythe screen poles down with'it, and

through the connection of the screen poles rwith the mat and with the longitudinal bars 9 and the spacers 12, the screen poles will be rmaintainedin substantially the same relation the force of the water, may bunch 'together andthus materially reduce the effectiveness of said poles asa screen.V

' As the mat finally settles upon the'bed of the stream, theV protruding and `preferably sharpened lower ends ot the screen poles will be: embedded in the bed ot' the stream and thus cooperate to a degree in holding the screen polesv in proper relationship. The upper endsy of the screen `poles under the pressure oit the water, will abut against the upper rowsv ot' biaces 2, and after the mat has permanently settled, the said ends of the poles are nailed or otherwise secured in position asA shown at 14, in Figures 1 and 2.A lt will be. apparentthat `with the method )of construction described in this appli-cation,

it will be possible to properly anchor the screen poles to the mat even it. the water levelv has risen to an extentto substantially sub'- merge the mat and tie' poles thereon, 'andk it is to be understood .that While-Ithave described and claimed the methodiof construction which is `preferable underv conditions of rising water. as mentioned, resort may be had to changes or modificationsr without departure' from the spiritfand scope of theappended claims. 1 l i i. yW'hatjI claim isz? 1; The method of producing a dike in a stream, comprisingy the sinking 'of upright piles'to a sutiicient depth in the bed of the streamior their proper anchorage, the for-` lstream for 4their secure anchorage, the forinationr of a mat around vand betweenl the;
